Veggie,
I've read many of your posts over the last two years and you seem to be very knowledgeable and legal oriented. Some of your research has been outstanding.
I'm not a career politician at all; my service ended years ago.
As far as the second amendment is concerned, it appears, and I underline the word appears, that my constitutional rights may be diminished as I can no longer carry in as many places as I once could if I respect the business owner's wishes. This is my only concern.
I hope this all works out as far as the gun buster signs.
Have you thought about approaching the owners of these local, small town businesses and politely tell them you've been carrying concealed in their establishments for years, and that with their permission, you'd like to continue doing so? A gunbuster sign is a generic sign addressing the public at large. They carry the weight of trespass only, and only then if the owner presses the issue and you refuse to leave. If the owners invite you to continue shopping there with the knowledge that you will be carrying, the signs no longer apply to you. If they refuse, then you'll know where they stand, which is against your constitutional rights, period!
